15.4.10 ACKNOWLEDGE SEQUENCE TIMING
An acknowledge sequence is enabled by setting the
Acknowledge
(SSPCON2 register). When this bit is set, the SCL pin
is pulled low and the contents of the Acknowledge Data
bit (ACKDT) is presented on the SDA pin. If the user
wishes to generate an acknowledge, then the ACKDT
bit should be cleared. If not, the user should set the
ACKDT bit before starting an acknowledge sequence.
The baud rate generator then counts for one rollover
period (T
high). When the SCL pin is sampled high (clock arbitra-
tion), the baud rate generator counts for T
SCL pin is then pulled low. Following this, the ACKEN
bit is automatically cleared, the baud rate generator is
turned off and the MSSP module then goes into IDLE
mode (Figure 15-17).
15.4.10.1 WCOL Status Flag
If the user writes the SSPBUF when an acknowledge
sequence is in progress, then WCOL is set and the
contents of the buffer are unchanged (the write doesn’t
occur).

15.4.11 STOP CONDITION TIMING
A STOP bit is asserted on the SDA pin at the end of a
receive/transmit by setting the Stop Sequence Enable
bit, PEN (SSPCON2 register). At the end of a
receive/transmit, the SCL line is held low after the fall-
ing edge of the ninth clock. When the PEN bit is set, the
master will assert the SDA line low. When the SDA line
is sampled low, the baud rate generator is reloaded and
counts down to 0. When the baud rate generator times
out, the SCL pin will be brought high, and one T
(baud rate generator rollover count) later, the SDA pin
will be de-asserted. When the SDA pin is sampled high
while SCL is high, the P bit (SSPSTAT register) is set.
A T
is set (Figure 15-18).
15.4.11.1 WCOL Status Flag

is in progress, then the WCOL bit is set and the con-
tents of the buffer are unchanged (the write doesn’t
